CANMAT MAB Flashcards
Tx PO de l’agitation en manie
a loading dose of divalproex, oral formulations of atypical antipsychotics, conventional antipsychotics such as haloperidol or loxapine, and/or benzodiazepines such as lorazepam may be appropriate
Tx IM de l’agitation
Because of the strength of evidence for efficacy in alleviating agitation in this population,
aripiprazole IM (level 2)
lorazepam IM (level 2)
loxapine inhaled (Level 1) olanzapine IM (level 2)
are recommended as the first‐line option.
2e ligne:
Sublingual asenapine (level 3)
haloperidol IM (level 3)
haloperidol IM + midazolam IM (level 3)
haloperidol IM + promethazine IM (level 3)
risperidone ODT (level 3)
ziprasidone IM (level 3)
1ère ligne de tx monothérapie pour manie aiguë
Approximately 50% of patients will respond to monotherapy with significant improvement in manic symptoms within 3‐4 weeks
Lithium (level 1)
quetiapine (level 1)
divalproex (level 1)
asenapine (level 1)
aripiprazole (level 1)
paliperidone (level 1 for doses >6 mg)
risperidone (level 1)
cariprazine (level 1)
Overall, these agents show comparable efficacy.
1ère ligne de tx combiné pour manie aiguë
Quétiapine + Li/Di
Aripiprazole + Li/Di (niveau 2)
Risperidone + Li/Di
Asénapine + Li/Di (niveau 2)
recommended as first‐line treatment options with greater efficacy than monotherapy with lithium or divalproex alone, especially in those with higher index severity
Monothérapie vs tx combiné pour manie aiguë
In general, combination therapy is preferred to mood stabilizer monotherapy because clinical trials suggest that on average about 20% more patients will respond to combination therapy.
There is also some evidence to suggest the benefit of combination therapy compared to atypical antipsychotic monotherapy, although there are fewer trials. Specifically, lithium plus quetiapine showed superiority to quetiapine alone
2 agents avec niveau 1 d’évidence en monothérapie pour manie NR pour tx combiné
Palipéridone, Ziprasidone
Indication de tx combiné pour manie
Combination therapy with lithium or divalproex and an atypical antipsychotic is recommended when a response is needed faster, in patients judged at risk, who have had a previous history of partial acute or prophylactic response to monotherapy or in those with more severe manic episodes.
Manie avec éléments psychotiques: effet a/n du pronostic
At least half of manic episodes are characterized by the presence of psychosis, and theories suggest that it is a nonspecific feature which improves alongside underlying manic symptoms.
While the prognosis for patients experiencing mood‐congruent psychotic features may not differ from those with an absence of psychotic symptoms, limited evidence does suggest that those with mood‐incongruent features have a more severe illness with poorer long‐term prognosis
Dépression bipolaire: temps de réponse au traitement
Across several different medications for bipolar depression, early improvement (after 2 weeks) has been found to be a reasonable predictor of overall response, whereas lack of early improvement is a more robust predictor of non‐response

Dépression bipolaire: switch vs add-on
In principle, all things being equal, a switch is preferred over add‐on to limit the degree of polypharmacy, but the clinical reality is that medications may be helpful for some but not all components of the illness, and using rational polypharmacy via add‐on treatments is often required. For situations in which patients experience a depressive episode while already receiving an adequately dosed antidepressant, strong consideration should be given to discontinuing or switching the class of antidepressant, unless clear benefits are apparent in reducing the severity or frequency of depressive episodes.

Risques de récurrence MAB associé à quels facteurs
With treatment, 19%‐25% of patients will experience a recurrence every year, compared to 23%‐40% of those on placebo.
Risk factors for recurrence include younger age of onset,
psychotic features
rapid cycling
more (and more frequent) previous episodes
comorbid anxiety
comorbid SUD
Persistent subthreshold symptoms also increase risk for subsequent mood episodes, and the presence of residual symptoms should therefore be an indicator of a need for further treatment optimization.
Availability of psychosocial support and lower levels of stress are also protective against recurrence.
Tx maintien MAB
Lithium (level 1), quetiapine (level 1), divalproex (level 1) and lamotrigine (level 1) monotherapies have the best combination of clinical trials, administrative data, and clinical experience to support their use as first‐line therapies for maintenance treatment of BD.
Recent data suggest that asenapine (level 2) is effective in preventing both manic and depressive episodes, and thus is recommended as a first‐line treatment. Finally, aripiprazole oral (level 2) or once monthly (level 2) is also recommended as a first‐line monotherapy in view of its efficacy in preventing any mood or manic episode as well as its safety/tolerability profile, although it has not been shown to be effective in preventing depression
Additional combination therapies included as first‐ line include quetiapine adjunctive therapy with lithium/divalproex (level 1) which has demonstrated efficacy in preventing any mood, manic or depressive episode. Aripiprazole plus lithium/divalproex (level 2) should also be considered as a first‐line option.
Quand peut-on utiliser des ISRS en MAB II?
Si dépression pure (non-mixte) et pas d’antécédent de virage hypomaniaque
Tx hypomanie en MAB II
Clinical experience suggests that all anti‐manic medications are also efficacious in hypomania. Thus, when hypomania is frequent, severe, or impairing enough to require treatment, clinicians should consider mood stabilizers such as lithium or divalproex and/or atypical antipsychotics. N‐acetylcysteine may also be of benefit, but further studies are needed.
